A TIDALLY DISRUPTING DWARF GALAXY IN THE HALO OF NGC 253 [PDF]

open access: yes, 2015
We report the discovery of Scl-MM-Dw2, a new dwarf galaxy at a projected separation of ∼50 kpc from NGC 253, as part of the Panoramic Imaging Survey of Centaurus and Sculptor project (PISCeS).

A dwarf galaxy remnant in Canis Major: the fossil of an in-plane accretion onto the Milky Way

open access: yes, 2003
We present an analysis of the asymmetries in the population of Galactic M-giant stars present in the 2MASS All Sky catalogue. Several large-scale asymmetries are detected, the most significant of which is a strong elliptical-shaped stellar over-density ...

Lactea: Web‐Based Spectrum‐Preserving Multi‐Resolution Visualization of the GAIA Star Catalog

open access: yesComputer Graphics Forum, Volume 44, Issue 3, June 2025.
Abstract The explosion of data in astronomy has resulted in an era of unprecedented opportunities for discovery. The GAIA mission's catalog, containing a large number of light sources (mostly stars) with several parameters such as sky position and proper motion, is playing a significant role in advancing astronomy research and has been crucial in ...

The High-mass X-Ray Binary Luminosity Functions of Dwarf Galaxies

open access: yesThe Astrophysical Journal
Drawing from the Chandra archive and using a carefully selected set of nearby dwarf galaxies, we present a calibrated high-mass X-ray binary (HMXB) luminosity function in the low-mass galaxy regime and search for an already hinted at dependence on ...

ANTLIA B: A FAINT DWARF GALAXY MEMBER OF THE NGC 3109 ASSOCIATION [PDF]

open access: yes, 2015
We report the discovery of Antlia B, a faint dwarf galaxy at a projected distance of ∼72 kpc from NGC 3109 ( M V ∼ − 15 mag ?> ), the primary galaxy of the NGC 3109 dwarf association at the edge of the Local Group.

Abundance ratios in dwarf elliptical galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2017
We determine abundance ratios of 37 dwarf ellipticals (dEs) in the nearby Virgo cluster. This sample is representative of the early-type population of galaxies in the absolute magnitude range -19.0 < Mr < -16.0. We analyze their absorption line-strength indices by means of index-index diagrams and scaling relations and use the stellar population ...

HyperFLINT: Hypernetwork‐based Flow Estimation and Temporal Interpolation for Scientific Ensemble Visualization

open access: yesComputer Graphics Forum, Volume 44, Issue 3, June 2025.
Abstract We present HyperFLINT (Hypernetwork‐based FLow estimation and temporal INTerpolation), a novel deep learning‐based approach for estimating flow fields, temporally interpolating scalar fields, and facilitating parameter space exploration in spatio‐temporal scientific ensemble data. This work addresses the critical need to explicitly incorporate

PEARLS: A Potentially Isolated Quiescent Dwarf Galaxy with a Tip of the Red Giant Branch Distance of 30 Mpc

open access: yesThe Astrophysical Journal Letters
A wealth of observations have long suggested that the vast majority of isolated classical dwarf galaxies ( M _* = 10 ^7 –10 ^9 M _⊙ ) are currently star forming.

Probing the low surface brightness dwarf galaxy population of the virgo cluster [PDF]

open access: yes, 2015
We have used data from the Next Generation Virgo Survey to investigate the dwarf galaxy population of the Virgo cluster. We mask and smooth the data, and then use the object detection algorithm SExtractor to make our initial dwarf galaxy selection.

Draco, a flawless dwarf galaxy

open access: yes, 2006
The Draco dwarf spheroidal galaxy (dSph), with its apparent immense mass to light ratio and compact size, holds many clues to the nature of the enigmatic dark matter.
